i This invention relates to improvements in water or otherfluid turbines,"-and has forv one of its principal'objects the provision of agturbine adapted'to be operated by the force ofrunning water or the like, and which will more efciently utilize .the'potential and kinetic energy available.- l

One ofthe important objects lof this invention'is to provide, in-ajwater turbineor the like, means for eliiciently and accurately controlling the flow ofY watergthroughthe turbine itself with a view'to utilizing power' as desired. v

VAnother important object of the invention is the provision, in a water turbine or the like, of a novel and more eflicient form of rotor, which will more effectively utilize the kinetic' energy ofthe running water andv which will at the same time provide for av proper distribution and elimination of spent water by means of centrifugal force. Still another and further important object of the invention is to provide, in a water turbine or the like, means for delivering several distinct elements or streams of waterfto a rotor provided with blade-like faces, so that the resultant efficiency of the turbine will be greater than that heretofore t line 2 2 of Figure 1, looking in the direction indicated by the arrows.

Figure 3 is a sectional view, taken on th line 3 3 of- Figure 1, looking in Vthe direction indicated.

Figure 5 is a perspective viewv showing the improved rotor of the invention.

As shown in the drawings: The reference numeral 10 indicates genbody of the improved water turbine of this invention. As illustrated in Figure l, the

" casing 10 is adapted to be' attached or seor the like 12, behind" which yis. maintained,

-As best illustrated in Figures 'l1 Iand 2,'th`e' rear portion of the casing 10 is in the form ...cured to the outerA face of Vthe wall of; a Y

of a disk, 16 having 'aA number ofl openings f therethrough and adapted to co-operatefwith v the disk 16 is a complementary rotatable gate element .1S-having a rack-20 formed y"in a por-- tion o f its periphery, ,withl which rack cooperates a worm wheel 22j'mo'u`nted on an Y operating shaft l24 adapted to be manually controlled by means of a handwheell-or the like 26. The hand wheel 26 is,-as shown in "Figure 1, positionedadjacentthe top ofthe *dam 12. In this Waythe flow of water to the turbine itself can be accurately and e'ff-ectively controlled `and regulated.

The main body casing 10 is formed with i a plurality'of spiral passages 28 therein, as best indicated in Figure 1, these passages` leading Vfromv acommonfopening' and terminatingat various points adjacent the for# l ward end'of the casing and adapted to 'de- `liver the water passing therethrough directly onto'the blade-like surfaces of airotor 30 formed in the shape of alfrustrum of akcone, as indicated in Figures 1 and 5." The rotor l t may be made hollow for purposes of lightness, but the ends are closed to prevent' un-V desired passage of water therethrough. The relationV between thenozzles or outlets of the passages 28 and-the blades 32 of they rotor 30 is such that Vthe waterissuing from the opening 28 will impinge upon the blades 32 at substantially right angles, therebyiaffording'the greatest possible measure of efliciency. y l

VAs will be noted, the larger base vof the Y rotor 30 is positioned adjacent the outlet of thercasing 10, thereby providing for a ready v elimination ofA spent water, the same being thrown o andoutwardly by the centrifugal force developed by the rotation of the rotor itself.' f

A suitable outlet nozzle orthe like 34 is .los

provided attachedto the casing 10 by means outlet nozzle 34C is positioned a suitable bearing 38 provided for supportingone end of a shaft 40 upon which the rotor 3 0is mount-` ed, the other end of the shaft 4Q being positioned in suitable lbearings 42 ,in the casing 10. Attached to the' inner end of the shaft with a similar beveled gear 46 mounted on Aof bolts and nuts 36 or the like, and' in this i Ali f 40 is a beveled gear 4:4 which co-operates l VVgenerated by the rotation Yofthe rotor 30 Y can be conveniently taken 0H and utilized.
